Subjects or/and subjects’ parent(s)/Legally Acceptable Representative(s) [LAR(s)] who, in the opinion of the investigator, can and will comply with the requirements of the protocol.

• Written or witnessed/thumb printed informed consent obtained from the subject/parent(s)/LAR(s) of the subject prior to performance of any study specific procedure.
• Written informed assent obtained from the subject (if applicable) prior to performing any study specific procedure.
• A male or female between, and including, 10 and 25 years of age (i.e. 25 years + 364 days) at the time of the first vaccination.
• Healthy subjects as established by medical history physical examination and clinical judgment of the investigator before entering into the study.
• Subjects who are either unvaccinated with MenACWY vaccine or have received a single previous dose of MenACWY vaccine can participate in the study, if they have received it at least 4 years prior to informed consent and assent as applicable (with the exception of meningococcal C vaccination, if the last dose of MenC was received at ≤24 months of age).
• Female subjects of non-childbearing potential may be enrolled in the study. Non-childbearing potential is defined as pre-menarche, current bilateral tubal ligation or occlusion, hysterectomy, bilateral ovariectomy or post-menopause*.
• Female subjects of childbearing potential may be enrolled in the study, if the subject:

Medical conditions

• Current or previous, confirmed or suspected disease caused by N. meningitidis.
• Household contact with and/or intimate exposure to an individual with laboratory confirmed N. meningitidis infection within 60 days of enrolment.
• Progressive, unstable or uncontrolled clinical conditions.
• Clinical conditions representing a contraindication to intramuscular vaccination and blood draws.
• Any neuroinflammatory, congenital neurological conditions, encephalopathies, seizures. History of febrile convulsions should not lead to exclusion.
• History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s)/product(s).

Hypersensitivity, including allergy, to any component of vaccines, including diphtheria toxoid (CRM 197) and latex medicinal products or medical equipment whose use is foreseen in this study.

• Abnormal function or modification of the immune system resulting from:

Administration of long-acting immune-modifying drugs at any time during the study period (e.g. infliximab).

• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination. Prior/Concomitant therapy
• Use of any investigational or non-registered product other than the study vaccine(s)/product(s) during the period starting 30 days before the first dose of study vaccine(s)/product(s) (Day -29 to Day 1), or planned use during the study period.
• Previous vaccination against any group B meningococcal vaccine at any time prior to informed consent and assent as applicable.
• Administration of immunoglobulins and/or any blood products or plasma derivatives during the period starting 90 days before the first dose of study vaccine/ product or planned administration during the study period until the post-vaccination 3 blood sample (Visit 6).
• Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 90 days prior to the vaccine/product dose(s) until the post-vaccination 3 blood sample (Visit 6). For corticosteroids, this will mean prednisone ≥20 mg/day (for adult subjects) or ≥0.5 mg/kg/day (for paediatric subjects), or equivalent. Inhaled and topical steroids are allowed. Prior/Concurrent clinical study experience
• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product. Other exclusions
• Child in care.
• Pregnant or lactating female.
• Female planning to become pregnant or planning to discontinue contraceptive precautions.
• History of /current chronic alcohol abuse and/or drug abuse as determined by the investigator.
